Add support for manually supplying Bedrock resource packs (#1076)

Browse source 
* send resource packs

A lot of this code is nukkit-credits in the classes

* send resource packs

A lot of this code is nukkit-credits in the classes

* Remove unnecessary code/debugs

* use separately generated hashes

* Updated mappings and added .mcpack support

* "packs" directory auto-create (#484)

* "packs" directory auto-create

* cleaned indentation in ResourcePack.java

* Cleaned ResourcePack.java

* Another cleanup

I hate editor on github.

* Yet another

* Another indentation cleanup

* Fix resource pack loading

(cherry picked from commit f93b07491e)

* Move back to internal sha256 hashing

(cherry picked from commit 812a3d82b2)

* Add resource pack loading back after merge

* Add comments, config option and removed unused files

* Fix packs folder location and cleanup code

* Move to better options for the client

* Fix typos in comments

* Fix pack loading

* Try to make it compile

* Final touches?

* Add Javadoc for MathUtils#constrain
